In this paper, to be closer to the realities of the relativistic heavy ion collisions than the thermal equilibrium assumption often used in the calculations of baryon number susceptibilities, the creatures of the collisions are treated as isotropic systems with temperature gradient. In addition, the quarks are thought as the quasi-particles with thermal masses. By doing these and according to Boltzmann transport equation, we get our results of the experimental observables Sσ and κσ2. We found that the results show a gap in value and a centrality dependence, which might indicate the relation between the baryon number susceptibilities and the temperature gradient in QGP.
